of the sun, the stronger the sunlight is, the more powerful the
wind blows, up to 750m3/h.
4.Intelligent temperature control without manual operation. It
starts working when temperature is above 77℉ and stops below 73.4℉.
5.High-quality solar panel, heat resisting, high pressure
resistant, stable, and long service life.
6.Sealed shell design. Anti- UV material is added in the outside
shell. Perfect weather fastness, durable.
7.Multiple protective devices, waterproof, insect prevention, rat
proof and sundries proof.
temperature controlling: When the attic’s temperature is equal to
or higher than 77℉-84℉, it will automatically switch on the fan.
